摘要：

Pulsed-EPR spectroscopy was used to study a modified C-60 molecule (1) in its photoexcited triplet state. The analysis of the triplet EPR lineshape shows a break of the high symmetry of the lowest populated triplet state of C-60 due to the modification of the C-60 unity. The reported temperature dependence of the spectra is influenced by relaxation effects. Lineshape simulations based on a triplet Hamiltonian including anisotropic T-1/T-2 relaxation were performed. The results are discussed in relation to the behaviour of pure C-3(60).
